SPECIFIGATION forming part of Letters Patent No. 681,165, dated August 20, 1901. Application filed MaylB, 1901. Serial No. 60,274. (No model.)

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIO E. KIP, residing I 5 at Montelair, Essex county, New Jersey, citizens of the United States, have invented certain new and usefulImprovements in Weft Controlling and Replenishing Mechanism for specifica- This invention relates to electromechanical I means for controlling the weft or filling of looms, and is applicable toweft-replenishing mechanisms, to which it is herein shown as I applied.

The invention alsoincludes means for outi ting or parting the weft-thread and weft end at proper times and means for holding the weft-thread coming from the discarded bob zo bin or weft-holder, so as to prevent it from being drawn into the shed .by the shuttle on I its next pick. I

Before proceeding to minutely describe the present invention it may be well to state that the loom, as herein shown, is provided with a suitable magazine to supply weftmagazine and driver, being like those shown ing the driver of the replenishing mechanism at the next beating-up movement of the lay. When the weft holder is driven'out of the shuttle by the incoming weft-holder from the magazine, a gripper holds the strand of yarn still connecting the discharged andsubstantially exhausted bobbin with the shuttle and prevents this strand of yarn from being carried by the next pick into the warp-shed along with the yarn from the full Weft-holder in the shuttle, thereby producing a fault in the goods; and the weft parter or cutter serves to sever both the weft-thread from the 6 and 7 are the two shuttle-boxes on the lay, the former at the left, wherein the twopole feeler plays, and the latter at the right, where the magazine is situated.

At the" right-hand side of the loom, as herein shown, is situated the magazine 8, supported rotatively in brackets in a known way on the loom-frame and carrying bobbins or weft-holders 9. As this magazine and its appurtenances are well known in looms it will suffice here to say that the bobbins 9 rest at their ends in suitable bearings in the respective heads or ends of the magazine and are brought one by one by suitable and known mechanism into position over the shuttle-box 7, from which bearings they are driven by a driver 10 down into the running shuttle 11 in the box at intervals as the weft or filling in the shuttle becomes substantiallyexhausted. The driver is held normally in its elevated position by a spring 12 and is actuated to drive out the bobbin by means that will be explained more in detail and with especial reference to Figs. 4, 5, 6, 7, and 7.

13 is the ordinary weft-fork, and 14: its slide.

15 is the ordinary knock-off lever, and 16 the shipper-lever. These are common on many looms.

17 is a slide mounted on the breast-beam and carrying an armature-lever 18, in one arm of which is a slot 19. An electromagnet 20 is carried by a bracket 21 and has its poles located directly over the armature on the lever 18.

The weft-hammer 22 has two branches 23 and 24. The former actuates the slide 14 of the 'weft fork, and the latter at proper times actuates the slide 17-that is to say, normally the armature falls away from the poles of the magnet 20, and thus elevates the slotted arm of the lever 18 above the vibrating branch 24. of the weft-hammer; but when said magnet is excited the slotted arm of the lever 18 is depressed, the branch 24 of the vibrating weft-hammer engages the slot 19, and the slide 17 is moved. In moving the end of said slide impinges on an upright arm 25 on a rockshaft 26, which extends across the front of the loom and rocks said shaft. This shaft carries on its end, at the right-hand side of the loom, an arm 27, which is coupled by a link 28 to a dagger 29,pivotally hung on an upright arm 30, pivoted at its lower end 31 on the loom-frame. The rocking of the shaft 26 by the slide 17 under normal conditions elevates the arm 27, and this brings the dagger 29 up to such a position that when the lay beats up the end of the dagger is impinged upon bya dagger-bracket 31 on the lay, thus causing the dagger to swing the arm 30 forcibly. This arm 30 is coupled at its upper end by a link 32 to an arm 33, fixed on or to the driver 10, and thus the forcible and sudden movement of the arm 30 actn'ates the driver and causes it to descend and drive a weftholder from the magazine down into the shuttle in the box below, the incoming weftholder knocking out the substantiallyexhausted holderfrom the shuttle. It may hap= pen for some reason that the shuttle when picked from the opposite side will not properly enter the box 7 that is, will fall short of en' tering far enough to properly receive aweft= holder from the magazine when one is to be supplied. In such a case it is important to provide means for preventing the driver from being operated, and this means, which is in the nature of a precautionary device, will now be described.

Playing upright and loosely through an ap erture in the lay at the proper point is a rod 34, which carries or may carry a roller 35 on its pendent lower end. Normally this rod drops until its head or upper end is flush with the raceway, Fig. 7, its lower end being in the same vertical plane with the arm 27 ,which has an inclined cam-surface 36 on its prolonged free end. As the lay swings to and fro normally the roller 35 swings over the depressed arm 27, Fig. 7, without touching it; but if said arm be elevated by the rocking of the shaft 26 the rod 34 will be driven'upward. This may occur, of course, when the shuttle to be supplied with weft is properly home in the shuttle-box 7. If, however, the shuttle is not home, but over the upper end of rod 34, the latter cannot rise, and consequently the arm 27 cannot rise. Therefore the dagger 29 Will not be elevated, and no bobbin will be driven out of the magazine by the driver. In order to permit the shaft 26 to rock without actuating the arm 27 when the latter is held down by the rod 34, the said arm has a stiff spring connection to the shaft 26, as seen in Fig. 5, the coupling-spring 37 being amply strong enough to lift the arm 27, the dagger 29, and the coupling-link 28. Normallythe spring 37 is not under tension, and by its resistance to change by torsion it holds the arm 27 steadyin its normal position with respect to the shaft 26.

The lay is provided with a weft parter or cutter which when the weft is replenished acts at two successive picks of the loom, or, more exactly, at two successive beats of the lay. The first action of the cutter is to sever the thread or yarn of the discarded weftholder at or near the selvage, and the second action is to sever the weft end from the weftholder just supplied to the running shuttle. This weft-parting mechanism will now be described with especial reference to Figs. 7, 7, 8, and 8*.

Mounted pivotally on the lay at 38 is a knife or blade 39,which stands normally upright at the end of the reed and cuts down across the raceway into a slot in the lay. The heel of this blade below the pivot 38 has a slotted connection to the upper end of an operatinglever 40,- fulcrumed at its lower end on the lay-sword. Mounted to play in an inclined bearing through the lay is a yielding or slid ing dagger 41, the rear end of which has a slotted connection to the lever 40. When this dagger is driven rearward the effect is to drive ,where it is designed to impinge upon the yield ing dagger 41,with two notches 44, one above the other. The front arm of this lever extends over a stirrup on a stirrup-arm 46, hung on the same pivot with the dagger-lever. Springs 49 and 48 tend,respectlvely, to hold 1 down the arm 46 and the lever 43, as clearly shown. A link couples the stirrup arm with the arm 27. Now it will be noted that when the arm 27 is elevated to put the dagger 29 in position for operating the driver on the 1 next beat up of the lay the link 50 will elevate the arm 46, and with it the front end of the dagger-lever 43,thus depressing the front end of said lever to an extent to put its lower notch 44 in the path of the dagger 41, and when the lay heats up the efiect will be to operate the blade 39 to cut off the weft thread or yarn eoni heating the discarded bobbin with the sel-' vage; but the dagger 41 moves back in operating theblade, and in moving back, owing to its engagement with the lowermost notch in the end of the dagger-lever, it depresses this notched end of said lever, turning the latter about its fulcrum and raising its front arm above the stirrup 45. Now when the lay next recedes the dagger 41 of course withdraws and a suitable spring 51 returns the blade 39 to its lay the blade may be again operated. This detaining device is best seen in Figs. 7 to 8*, and it consists of a pendent latch-detent 52,

f jhung from the breast-beam above and pro- 1 vided with a shoulder 53 and a spring 54.

This latch-detent depends through a slot in the lever 43, which slot has an inclined front end 47, upon which the curved end of the latch may bear like a cam. In the side I of the latch-detent is a stud or pin 56, and with this pin may engage at proper times a 5 gravity-dog 57, mounted on thelever 43 and having a shoulder 58 to engage the pin 56. Normally the parts occupy the positions 1 seen in Figs. 7 and 8. U H 1 1p end of lever 43 is depressed through the elei. the lower notch 44 is brought into the path When the notched vation of the arm 27 and the stirrup-arm 46,

blade 39 to sever the weft-thread from the As the inof the dagger 41.

the lever 43 causes the shoulder 53 on the latch-detent 52 to take over the lever 43 and hold it depressed as the lay recedes, and when the lay next beats up the dagger 41 engages the upper notch 44 of the lever 43 and is driven back, thus causing the blade 39 to descend and sever the weft end from the fresh weftholder supplied'to the shuttle. The backward movement of the inclined dagger 41 in operating the blade depresses the lever 43 still farther, and the inclined front end 47 of the slot in the lever 43, acting on the hooked extremity 55 of the latch 52, presses the latter back until the shoulder 58 on the dog 57 engages the stud 56 on the latch and holds the latter back out of engagement. This is the position seen in Fig. 8 recedes,the lever 43 flies up quickly under the influence of its spring 48 and trips the dog 57, thus allowing the parts to assume again their normal position.

The shuttle employed in this class of replenishing mechanisms is usually selfthreading, and when the bobbin is knocked down and out of it the thread from the bobbin still remains engaged in the eyeof the shuttle, and the weft end from the incoming shuttle also passes into this eye. From this it frequently results that although the thread from the outgoing bobbin is cut or parted from the selvage of the goods in the loom, this thread is liable to be held by the shuttle and carried back into the warp-shed, thereby producing a fault in the fabric. To avoid the possibility of this occurring, a gripper is provided to seize and hold the thread from the discarded bobbin long enough to draw it from the eye of the shuttle when the latter is next picked. This gripper device, which is illustrated in Figs. 2, 3, 6, 7, and 7, will now be described.

On the under side of the lay, adjacent to the aperture (59 in Fig. 2) through which the bobbin falls from the shuttle, is a gripperjaw 60, preferably pivoted at 61, so that it will adjust itself to the operative jaw 62 of the gripper, which is pivoted at 63. The jaw 62 is backed by a suitable spring 64, which keeps it pressed up elastically to the jaw60 normally. The jaw 62 is coupled by a link 65 to the lever 40, which operates the blade 39, so that when the dagger 41 is first pressed back in severing the thread from the discarded bobbin the jaw 62 will be pressed back to the opposite side of the aperture 59, so that the discarded bobbin passes out and down between the jaws 60 and 62, and as the lay recedes the spring 64 will close the jaw 62 on the bobbin-thread and clamp it up to the jaw 60. Thus this thread will be held fast until the next pick of the shuttle frees the waste thread from the latter. Oneside of theshuttle-box 7 is omitted from Fig. 2, so as to betthe gripper-jaws.

The manner of closing the controlling electric circuit and the means employed in effect- When the lay next ing such closure will now be described, with especial reference to Figs. 1, 4, 11, and 12.

Referring first to Fig. 4, which shows the shuttle 11 and the bobbin or weft-holder therein, 66 designates the metal jaws in the shuttle, which grip metal rings 67 on the bobbin 68 in aknown way. These rings embrace a metal sleeve or thimble 69 on the bobbin, which thimble may extend down over the tapered and stepped portion of the bobbin. This thimble is seen in section in Fig. 18. In the shuttle, at its side, is mounted a contactspring 70, secured to the shuttle at 71 and its free end extending over or part way across an aperture or way .72 in the side of the shut tle. When the shuttle is in place in the box, this aperture 72 registers with a suitab-leopening or way 73 in the adjacent side of the box. The filling on the bobbin is indicated by dotted lines in Fig. 4.

Referring now to Figs. 4, 11, and 12 more especially, the contact devices or two-pole feelers will be described.

74 is a generator, and 75 represents the conductors, of an electric circuit which includes the magnet 20 and said generator. The terminals 76 and 77 of this circuit are mounted on andinsulatedfromtheloom-frame. These terminals are or may be alike, and one of them is illustrated in Figs. 11 and 12. To make the terminal yielding, it is formed, by preference, telescopic, of two tubes, one within the other, the distending means being a spring 78 and spring-rod 79, situated inside the tubular parts. These terminals are placed, as seen in Fig. 4, so that when the lay beats up the terminal 76 will impinge upon a jaw 66 (or some other metal part) and the terminal 77 upon the spring 70, pressing the latter in against the filling on the weft-holder. The apertures 72 and 73 in the shuttle and box open a way to one of the jaws 66, so that the terminal 76 may impinge thereon. Now so long as there is a predetermined quantity of filling in the running shuttle the operatingcircuit will'not be closed; but when the filling has been exhausted in the weaving down to a predeterminedextent the circuit will be closed and the replenishing mechanism set for operation at the next beat up of the lay.

It may be explained here that in the construction of the contact devices seen in Fig. 4 the contact-spring 70 in the shuttle has or may have a slight contact protuberance 80 to touch the contact-thimble 69 when thefilling is sufliciently exhausted, and this protuberance may be varied as to the extent of its inward projection to suit the varying conditions of the case. With some yarns and with some fabrics the mass'of waste filling to be left on the bobbin will vary considerably. With other yarns no protuberance on the spring will be required, and we wish it understood that the condition of the spring can be varied in thickness, length, and shape to bestsuit the particular class of yarn being woven. What we have called a protuberance on the contact-spring or circuit-closer 70 may be, as shown in Fig. 4, a part of said spring bent or set out of line laterally with that part of said circuit-closer which bears on the weft in the shuttle.

One of the principal objections to the comnote the condition of the filling previous to its being entirely exhausted has been that no exhaustion-indicating feeler device has been produced with scope sufficient to permit it to be used equally well on wide and narrow looms or with fine, medium, or coarse weft and still leave in each of these varying conditions a minimum amount of weft or filling on the weft-holder. We have in our present device provided an exhaustion-indicating device which has the necessary scope and which by modifying the shape of the contact portion of the interposed circuit-closer may be used on any width of loom. and with any count of yarn and still leave the minimum quantity of weft to prevent an imperfection in the fabric. We therefore consider this feature of our invention important and novel and desire to claim it broadly.

Our two-pole feeler or exhaust-indicator may be employed in connection with a weftreplenishing mechanism wherein the shuttle is changed such, for example, as in our Letters Patent No. 636,704, of November 7,1899; No. 637,195, of November 14, 1899, and Nos. 637,695 and 637,753, of November 21, 1899.

Fig. 9 shows a shuttle 11 fitted up with our contact devices, the bobbin or weft-holder being mounted on a spindle therein. In this figure, which shows the weft-holder in section, 81 is the metal spindle in the shuttle, and this spindle is in electrical connection at its hinged end with the metal jaws or plate 82 in the shuttle. The spindle and the jaws 82 are common in shuttles. On the spindle is slipped a weft-carrier 68 which is a buttcop, as shown in Fig. 9. In thiscop is a metal tube 83 in contact with the spindle .on the one hand'and with the metal contact piece or stud 84 in the cop on the other hand. This stud 84 is normallycovered with the weft or filling 85 on the weft-holder. Obviously the stud 84 is always connected electrically with the jaws 82 through the spindle. Within the shuttle, as in the case before de scribed, is mounted the contact-spring 70, adapted to be impinged upon by the terminal 77, while the terminal 76 impinges upon one of the jaws 82 or some other metal part. The spring 70 in this case has its protuberance 80 adapted to impinge upon the stud 84 when the latter is uncovered by the filling.

Our two-pole feeler and contact devices may also be employed in a weft-replenishing mechanism where the weft-holder is mounted in a Weft-case, and the latter, with its exhausted weft-holder, is driven out of the running shuttle in the manner previously explained with respect to a bobbin. Our Patents No.

.mercial use on looms of weft-replenishing mechanisms having feeler devices which detion of our invention to a weft-case is illustrated in Fig. 10, which shows the shuttle 11 in longitudinal section. In this construction -86 is a weft-case having end pieces or journals 87, whereby it is mounted in jaws 88 in the shuttle. The weft-holder 68 is mounted in the weft-case precisely as the weft-holder .of Fig. 9 is mounted in the shuttle, and no special description will be required. It need only be saidthat the contact-spring 70 is mounted on the inner face of the weft-case and properly insulated therefrom, as both willusually be of metal. The weft-case will also be apertured or cut down at the side, so

as to admit the terminals 76 and 77. It will be noted that the movable spring orintermediate circuit-closing part 70 is limited in its movements by the weft or filling'in the running shuttle and positioned and controlled by the quantity of such weft or filling; also, that it insures the proper closure of the circuit so long as the shuttle is in the box at a point where the terminal feeler 77 may impinge upon some part of said circuit-closing spring. Being the first, as we believe, to employ such an intermediate circuit-closer on a weft-carclosethe controlling-circuit of exhaustionlndicating devices in a loom, we claim the same broadly. The UnitedStates Patentof Ohace, No. 633,97 6, of September 26, 1899, as

well as our pending application, Serial No.

64,246, filed June 12, 1901, show like electromechanical exhaustion-indicating devices for controlling an automatic weft-replenishing mechanism. and controlling mechanism for stopping the loom when the weft requires replenishing, and it will be obvious that our electromechanical exhaustion-indicating devices have-the same extent orscope of application.
